| 20090097873 | INTERMEDIATE ROLLER FOR SENSING TEMPERATURE OF PASSING SURFACES - A temperature sensing system for use in an electrographic printing machine senses temperature on a surface of a moving member. An intermediate roller is placed in operative contact with the surface of the moving member at a first location. A temperature sensor is then placed in operative connection with the intermediate roller at a location distanced and/or isolated from the moving member. A bias member is placed in operative contact with the temperature sensor to provide a force to the temperature sensor, resulting in the temperature sensor being biased against the intermediate roller, the temperature sensor thereby sensing the surface temperature of the moving member indirectly through the intermediate roller. | 04-16-2009 |
| 20090154968 | Ultra-Heated/Slightly Heated Steam Zones For Optimal Control Of Water Content In Steam Fuser - A dual-zone steam fuser for a xerographic system includes a ultra-heated first zone maintained at 200-500° C. that quickly heats a paper substrate to an optimal toner fusing temperature (e.g., 120-150° C.), and a second, relatively cool second zone for maintaining the substrate at the optimal temperature during completion of the fusing process. A conveying system conveys the substrate so that it exits the first zone and enters the second zone immediately after the substrate temperature reaches the optimal toner fusing temperature, and is maintained in the second zone for a predetermined fusing operation time period. The gas (e.g., steam) temperatures and timing are selected such that surface condensation is minimized during initial heating, and such that moisture content is normalized at the end of the fusing process. | 06-18-2009 |
| 20090154969 | Pressure-Controlled Steam Oven For Asymptotic Temperature Control Of Continuous Feed Media - A non-atmospheric pressure vapor oven system that utilizes a controllable pressure zone to facilitate fast phase change heat transfer at any desired temperature to heat or cool flat substrates, and to level temperatures across different locations of the substrates. The system enables the use of a heat transfer fluid, such as water, without being limited to a particular temperature, such as the fluid's natural boiling point at atmospheric pressure. The system includes a vapor oven (hermetic enclosure) defining a pressure chamber having sealed entry and exit ports for transferring an object (e.g., a sheet of paper) with added material (e.g., toner) through the pressure chamber, and a pressure regulation apparatus for setting the saturation temperature (boiling point) of heat transfer fluid inside the vapor oven to an optimal heating/cooling temperature by selectively controlling the pressure inside the hermetic enclosure. | 06-18-2009 |
| 20090160924 | CONTACTLESS INK LEVELING METHOD AND APPARATUS - A method of leveling ink that is printed on a substrate includes establishing a thermal gradient across a thickness of the substrate, the thermal gradient characterized in that it is less than a viscosity threshold temperature of the ink across most of the substrate. | 06-25-2009 |
| 20090195572 | System And Method For Leveling Applied Ink In A Printer - A system enables ink on an image receiving member to be re-distributed to reduce banding effects in the image. The system includes an ink applicator for applying ink to form an ink image on an image receiving member as it passes by the ink applicator; a plenum chamber for receiving a flow of pressurized fluid from a fluid source, and at least one opening in the plenum chamber to direct the flow of pressurized fluid from the plenum towards the ink image on the image receiving member to re-distribute the ink on the image receiving member. | 08-06-2009 |
